By using the definition of collinear and coplanar points, we will see that
- 7) Collinear points: All lie on the same line.
- 8) Coplanar points: All lie on the same plane.
What do collinear and coplanar mean?
We say that a given set of points is collinear if all the points belong to the same line, just to give an example, any pair of two points is collinear, as we always can find a line that passes through two points.
On other hand, a set of points is coplanar if the points lie on the same plane. Remember that a plane is defined by a line and a point outside of it.
With these definitions in mind, we can answer:
- 7) Collinear points: All lie on the same line.
- 8) Coplanar points: All lie on the same plane.
